Question

Find the area of the circle 42 in

Answer 1

Step-by-step explanation:

If the radius of the circle is 42 then:

$2\pi {r}^{2}$

$2 \times \frac{22}{7} \times 42 \times 42$

$2 \times 22 \times 6 \times 42$

$11088 \: sq. \: units$

if diameter is 42 then:

$2\pi {r}^{2}$

$r \: = \frac{d}{2}$

$2 \times \frac{22}{7} \times \frac{42}{2} \times \frac{42}{2}$

$2 \times 22 \times 3 \times 21$

$2772 \: sq. \: untis$
